electrical problem
Hi everyone,
While installing a oil temp gauge in my 1980, I accidently shorted the back side of the gauge. Immediately the tach started reading a baseline of 4500 RPM and the amp guage was pegged on discharge. Any ideas?

Re: electrical problem (ENCHANTMENT)
What is the problem right now? What you did was ground the amp guage which is hot at all times. Check the fuses and if blows, you should are ok. There may be a burt fusable link somewhere.

Re: electrical problem (silvervetteman)
Thanks for the reply Silvervetteman,
Right now the symptom is the amp gauge is pegged all the way on discharge and the tach is at 4500 RPM. What caused this to happen was I forgot that the ignition was on and I tried remove the plug in connector from behind the oil temp gauge and it touched the positive post of the oil temp gauge and arced. That is where I am right now. Any help would be humbly and gratefully appreciated.

Re: electrical problem (ENCHANTMENT)
OK... Are you saying that when the ignition is off the amp gauge is pegged -? If it pegs when you turn the key on then you have a direct short. If it is pegged all the time you may have destroyed the gauge. It is unlikely that there is a continuous short as fuses blow and wires burn when that happens. A pegged amp gauge indicates a HUGE current draw! Dis-connect the negative battery post and put a test light from the battery to the dis-connected terminal. Make sure everything is off including courtesy lights. If the test ligt lights there is a draw on the system. If not then there is no short in the off position at least. More info please

Silvervetteman,
Yes the gauge is pegged all the time. I have to go out in a few moments and I will disconnect the battery and trouble shoot it as per your instruction tomorrow. Thanks again!
